"Excellent crew. One crew came for an estimate and was able to get another crew in a little later to install. All the crew that handled the installation were professional, knowledgeable, amicable and capable. I did not shop around, so I cannot say whether the price was competitive, but I am very happy with the whole experience, including customer service reps."

"I recently had a water main installed by Next Level Plumbing, and I couldn’t be happier with the experience. From the start, they offered me a great rate compared to other companies in the Suffolk area, but what really stood out was the service. They were super helpful, attentive, and made sure all my plumbing needs were met in a timely fashion. Unlike other companies I called, this didn’t feel like “just a job” to them—it felt personal. They took the time to explain everything, made the process stress-free, and gave me the sense that they truly cared about the work and my satisfaction. It honestly felt like a relationship was built, not just a transaction. I’ll be recommending Next Level Plumbing to anyone I know who needs plumbing work done. They really do live up to their name—next level service all around! "

"We were blown away by the quality, efficiency of work, attention to detail and customer service of Precision Plumbing & Heating from the very first interaction and throughout the entire process. Over-the-phone and in-person James was professional, highly communicative and an absolute pleasure to work with. Our telephone call was responded to immediately. James came over the very same day to review our list of items we were considering having done. Clear and intelligent advice was provided and a reasonable quote was submitted the next day; work was scheduled for a couple of days later that was able to meet out tight deadlines for getting the work accomplished. The list was long...old corroded jumbled waste pipes, in danger of failure, were expertly replaced. A couple of old damaged faucets were replaced cleanly and professionally. A poorly situated refrigerator water line, originally improperly installed by a previous plumber, was re-routed correctly and in time for our painter to patch and paint the area. Other work included a check & tune-up of the Heating System, a review/check-up of the A/C System, and a handful of other minor plumbing issues rounded out the laundry list of items. A huge amount of work was done swiftly and efficiently in a couple of days. It cannot be emphasized enough...James was fantastic. His approach to the work we wanted done was beyond any experience we have ever had with any service professional. His advice was practical; he advised work that he would want as if it was his home being worked on. His work ethic was customer-focused and clearly above and beyond: "How late is too late for me to work this evening? I would like to finish as much as possible but want to make sure it doesn't impact you." James is all that and more...he is THE definition of the Yiddish word "Mensch" : a person of integrity and honor. We will definitely work again with James at Precision Plumbing & Heating."

"Hands down best contractor we have ever worked with and highly recommend. Anthony was honest and determined to repair our horrible plumbing that we have had problems with for years. At 61 years of age I know excellence and integrity and Anthony has both in loads. He is a master plumber and his work ethic far exceeded our expectations. Red Lion provided excellent expert service at a fair price and we are grateful to have e found them."

FAQs for water main install, replace or repair projects in Islip, NY

If you notice puddles or standing water in your yard, a sudden drop in water pressure, cracks forming in your foundation, frequent clogs in your plumbing fixtures, or water that looks or smells unusual, you might have a leak in your main water line. These signs mean it's time to call a professional to evaluate the issue and prevent further damage.

A professional water main inspection is a comprehensive evaluation performed by a licensed plumber who checks every section of your plumbing system. The inspection costs $165 and uses advanced diagnostic techniques to identify hidden leaks or wear. This service clarifies the exact condition of your water main, enabling precise repairs that prevent future damage and ensure the overall health of your plumbing system.

Protect your water main by scheduling a cleaning and inspection every two to five years. The average cost of a sewer line cleaning is $400. It’s also important to never dig in your yard without first calling the dig line (811) to ensure you don't accidentally hit the water or sewer lines. Watch for soil erosion, low water pressure, or wet spots in your yard, and take immediate action if you suspect a leak. Remember, the longer you leave it, the worse the problem gets and the more costly it is to fix.

When properly maintained, your water main is engineered to remain functional for 50 years or longer. A durable water service in excellent condition should consistently perform without major issues for half a century. In contrast, metal pipes exposed to acidic soil corrode faster, whereas modern plastic pipes resist corrosion and function for decades beyond metal alternatives. Regular maintenance and inspections are essential for confirming your system’s longevity.

No, homeowners insurance does not cover the cost to repair a water main. Insurers fund only sudden, unforeseen events like a burst pipe and exclude gradual issues or normal wear and tear. Damage resulting from leaks, such as mold remediation or property claims, is not covered. It is essential to contact your insurance provider immediately to confirm your policy’s details and any potential adjustments needed.
